I Specification of Iletters Patent.

Patented May 4., 1909.

Application filed January 6,: 1909. Serial ,No. 471,002.

To all whom it mayconcem:

Be-it known that 1, Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in- Gar- Underframes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in car underframes and more particularly-to such as are adapted "for use with cars in which the superstructure is supported upon the pedestals.

The object of the invention is to provide an underframe which will be very rigid and strong and yet comparatively light and which shall be adapted to be connected with the pedestals of a car without the use of a continuous flanged member carried by the pedestals. 1 I

With this object in view the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of a portion of a car underframe embodying my improvements. Fig. 2 is a transverse sectional view on the line wa: of Fig. 1. Fig. 3 is a sectional View on the line g y of Fig. 1. Fig. 4: is a section on the line view illustrating a slight modification,

1 represents a center girder which may comprise two channel members 2, 2, which extend from one end sill 3 to the other and a cover plate 1 secured to the upper flanges of the center sill members and also extending continuously from one end sill 3 to the other. Angle irons 5 are secured to the inner faces of the center girder members in line with the lower flanges of the latter and serve to reinforce said girder members and the open space between said angle irons will aflord access between the girder members. End sill diaphragms 6 are secured to the center girder members some distance rearwardly of the end sills 3 and project laterally from the center girder members and at their outer ends said diaphragms 6 are provided with seats 7 for the accommodationof the ends of side sills. Channel pieces 8 connect the end sill diaphragms with the end sills at respective sides of the center girder.

AN 'roN BECKER, of-

.22 of Fig. 1, and Fig. 5 is a' seats angle members 24 are secured.

These channel pieces, together with the center girder members which project beyond the end sill diaphragms, serve to support the platform flooring 9, as

shown in Fig. 3. Atthe center of the underframe, trans verse diaphragms 10 are secured to the center girder members and project laterally therefrom, said diaphragms being provided at their outer ends with seats for the accommodation of the side sills of the car. A filler 11 maybe secured between the center girder members and in alinement with the diaphragms 10.

A cross beam 12 is located a short distance in rear of each end of the underframe and each of said cross-beams comprises two diaphragms'13, 13, at each side of the center girder and rigidly secured at their inner ends to the center girder members. Fillers 14 may be secured between the center girder members in alinement with the diaphragms of the cross beam. In addition to the diaphragm 13, the cross-beam 12 comprises a top cover plate 15 and a bottom plate 16 which pass-over and under the center girder. The cross beam 12 is made of considerable width, the diaphragms 13 thereof being so spaced apart as not to interfere with the car wheels when the pedestals are connected with the cross-beam in the manner which will now be explained.

- Inwardly removed from the outer end of the cross-beams 12 and between the separated members or diaphragms 13 thereof, a

flanged plate 17 is located. Each plate 17 is providedat its side edges with flanges 18 which are riveted to the diaphragms 13 and at "the lower edge, each plate 17 is provided with a flange 19 riveted to a shoulder 20 on a car pedestal 21. The pedestal 21 projects above the lower edge of plate 17 and is riveted to the latter as clearly shown in Fig. 2. Each plate 17 is provided at its upper end with a flange 22 and to these flanges the respective ends of the top cover plate .15 are secured.

The out-er ends of thediaphragms composing the cross-beams 12 are provided with seats 23 in line with the seats at the outer ends of the centerdiaphragms 10 and the end sill diaphragms 6 and on these alined Upon these angle members the side sills which may, in effect, be side furring strips 25 are located. Furring strips 26 are also supported upon the various crossbeam diaphragms so that their upper faces will. be in horizontal alinement with the upper faces of the side furring strips or sills 2'5.

111 Fig. 2 of the drawing the top of the center girder is substantially in horizontal alinement with the tops of the diaphragins of the cross-beams, but if desired, in order to lower the floor line of the car, the tops ot' the cross-beams may be dropped a sullicient distance so that the tops of the furring strips will be substantially in horizontal alinei'nent With the top of the center girder, but in such Construction itwould be necessary to slot the center girder members for the passage of the top cover plate 15. Such construction is shown in Fig. 5 of the drawrugs.

With my improvements the entire load is carried by the center girder and the latter is supported by the car pedestals through the medium of the cross-beams 12 and the plates or brackets 17 secured between the members thereof,-the use of continuous flanged members carried by the pedestals begin thus avoided.

Havingfully described my invention what I claim as new and desire to secure by Letters-Patent, is,

1. A car underframe, comprising a center girder, transverse members secured thereto and atl'ording supports for side sills, plates secured to said transverse members for supparting the under lraine upon a car pedestal, and cover plates secured upon said transrerse members and to the upper ends of said plates.

2. A c: r under-frame, comprising a center girder, transverse diaphragins projecting laterally therefrom and spaced apart, plates disposed between said diaphragms at points inwardly removed from the outer ends of the latter, each of said plates having flanges secured to said diaphragms, a cover plate extending over the center girder, and llanges on the upper ends o1 said plates and sevured to the said coyer plate.

3. The combination with center girder members, each ha ring outwardly projecting flanges at both edges, a continuous cover plate secured to the upper flanges ot the respective center girder members, and angje irons secured to the inner faces of the center girder members at their lower edges, of a cross-beam comprising parallel members spaced apart and secured to the center girder members, and means for connecting said cross-beam members with the pedestals ot a car.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
